Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

On the numerical solution of the multidimensional singular integrals and integral equations, used in the theory of linear viscoelasticity

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
In the present report, we investigate the formulation, for the numerical evaluation of the multidimensional singular integrals and integral equations, used in the theory of linear viscoelasticity. Some simple formulas are given for the numerical solution

Rheological properties of natural and disturbed structure samples of soddy-podzolic and agro soddy-podzolic soil

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2017
The rheological properties of two profile`s horizons of soddy-podzolic and agro soddy-podzolic soil were studied by the amplitude sweep test on a rheometer MCR-302 (Anton Paar, Austria) on samples of natural structure (pastes) and disturbed structure ...

Sulfation‐Tunable Peptide‐Glycosaminoglycan Hydrogels for Hematopoietic Stem and Progenitor Cell Expansion

open access: yesAdvanced Functional Materials, EarlyView.
Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.

Bioinspired Co‐Assembly Enables Multiscale Architected Hydrogels for 3D Printing With Integrated Antibacterial and Bioactive Functions

open access: yesAdvanced Functional Materials, EarlyView.
A multicomponent supramolecular hydrogel integrating cell‐adhesive and antibacterial peptides within an alginate‐cellulose nanofibril matrix is developed. Peptide co‐assembly simultaneously strengthens the hydrogel network, improves extrusion printability, and imparts cell‐adhesive and antibacterial functions, offering a versatile platform for ...

Imaging the Thickness‐Dependent Formation of Schottky Barriers in Metal–Semiconductor van der Waals Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Using nanobeam photoemission, we demonstrate imaging of the in‐plane and out‐of‐plane electric field landscape within a metal–semiconductor van der Waals heterostructure. We provide evidence for Schottky barrier formation that depends on the semiconductor thickness. ABSTRACT Achieving high‐performance optoelectronic devices based on two‐dimensional van

Non-Stationary Waves in Three Component Viscoelastic Bar

open access: yesМеханика машин, механизмов и материалов, 2016
In the paper we obtain exact analytic solutions of a problem on longitudinal shock on a thin, piecewise-homogeneous linear visco-elastic bar consisting of three parts of finite length h1(0 < x < l1), h2(l1 < x < l2) and a semi-infinite length (l2 < x < ∞)
